NAME

statd, rpc.statd - network status monitor

SYNOPSIS

/usr/sbin/rpc.statd

DESCRIPTION

statd is an RPC server. It interacts with

lockd to provide the crash and recovery functions for the lock-

ing services on NFS (see lockd(1M)).

statd keeps track of the clients with processes which hold locks on a server. When the server reboots

after a crash, statd sends a message to the

statd on each client indicating that the server has rebooted.

The client

statd processes then informs the lockd

on the client that the server has rebooted. The client

lockd then attempts to reclaim the lock(s) from the server.

statd on the client host also informs the

statd on the server(s) holding locks for the client when the

client has rebooted. In this case, the

statd on the server informs its lockd that all locks held by the

rebooting client should be released, allowing other processes to lock those ﬁles.

Options

statd recognizes the following options and command-line arguments:

-l log_file This is an obsolete option. All messages and errors are logged to

/var/nfs/rpc.statd.log

WARNINGS

The crash of a server is only detected upon its recovery.
